ATOMIZER.

SPECIFICATION forming part of Letters Patent No. 533,489, dated February5, 1895;

Application filed I'gbmary 12, 1894. $erial o. 49 9,892. (No model.)

To all whom it may concern:

Be it known that I, THOMAS EDWIN OGRAM, a citizen of the United States,residing at Washington, in theDistrict of Columbia, have inventedcertain new and useful Improvements in Atomizers; and I do declare thefollowing to be a full, clear, and exact descrip tion of the invention,such as will enable oth ers skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

My invention relates to improvements in atomizers, and it refers moreparticularly to that class of atomizers, having a fluid receptacle orholder, an air controlling stopper, having connected therewith asprayer, a storage bulb and a compression bulb, and such invention hasprimarily for its object to pro vide an atomizer of this character,which can be used either as a liquid or powder sprayer, in a simple,convenient and effective manner.

It has also for its object to provide an atomizer of this kind in whichthe stopper and its connected parts, including the air shifting valvedevices are, very compactly arranged, and of a very simple andinexpensive construction; and which can be readily detached and replacedwhen it is desired to clean the same.

Furthermore it has for its object to provide an atomizer of this classin which the compression and storage bulbs, as well as the operatingvalve are so arranged, relatively, that it can be the more convenientlymanipulated by the operator, and without danger of break ing any of theparts.

W'ith other minor objects in view, which hereinafter will be referredto, the invention consists in the peculiar and novel arrange ment andcombination of parts, as will be first described in detail and pointedout in the claims, reference being had to the accompanying drawings, inwhich-- Figure l is a perspective View of my improved atomizer, the samebeing arranged as a powder sprayer. Fig. 2 is a cross section of thesame on the line 2--2, of Fig. 3. Fig. 3 is a similar view of the sametaken on the line 33, Fig. 2, the fiuid spray nozzle being showninserted in dotted lines, and Fig. 4 is indicates a bottle or otherholder for the fluid when the atomizer is used as a liquid sprayer, andas asupplemental air chamber when used as a powder sprayer, and B thestopper, which in the practical construction is formed of any desiredmaterial preferably of hard rubber, and of any desired shape or form. Inthe drawings such stopper is shown as cylindrical, in the form of a plughaving a tapering extension Z) whereby it can be conveniently insertedin the mouth of the bottle, and such tapered portion may have an outerpacking portion whereby it can be tightly fitted in such bottle mouth.

In the upper end, centrally, the stopper has a valve chamber 0, havingan internal thread portion 0, which receives a screw cap D, which closesthe upper end of such chamber and serves as an abutment for a spring 61,which bears down on and normally closes a valve E over an opening F,which communicates with the central air chamber G which extendsvertioally down through the stopper, as shown, such valve E having itsstem e projected down into such chamber, the lower edge terminating in ataper or needle bearing e.

At the front the stopper has a diagonally disposed aperture or chamber Hopen at the top, and communicating with the central chamber G at thebottom, such chamber forming the discharge or spray tube channel, aswith it such spray tube is connected. In the construction shown a spraytube 1 having a short shank portion I is inserted in the upper end,which tube has at a point forward of its connection an orifice i in itstop, in which fits a holder, having a tapering apertured upwardlyprojecting month i formed with a cork or other packing shell, whereby abottle or other vessel can be fitted air tight into such month, asindicated in Figs. 2 and 4. When, however, it is desired to use theatomizer for spraying a liquid, the tube I is removed and a nonapertured tube having an extension I is inserted, which passes downthrough the bottom of the chamber G as indicated in dotted lines in Fig.3.

J, J indicate nozzle members formed at opposite sides of the stopper B,and projected at right angles to the front or spray tube channel, whichhave air orifices J, and J',respectively which discharge into thechamber 0 just under the cap D, and to one of such nozzles, J isconnected the compressing bulb K while to the other J is connected thestorage bulb K.

So far as described it will be readily seen that should the bulb K becompressed the air drawn in thereby will be forced through the nozzle Jinto chamber 0 and the storage bulb K, where it will remain as the valveE is held closed and the bulb K formed with the usual check valves (notshown).

In the rear the stopper has a valve chamber L projected at right anglesto the nozzles J, J, the base of which has an aperture Z which opensinto the chamber G and through which projects the stem m of a thumboperated valve M, which stem is wedge shaped or tapered at its end,normally projecting under the point of valve stem e as most clearlyshown in Fig. 3.

As a simple and convenient means of adjusting and holding such thumbvalve in place, such valve is provided with an annular flange m theouter edge m of which engages an internal annular flange on thecentrally apertured screw plug N, while the inner face of such flangeabuts a rubber cushion spring 0, which normally holds the button end ofthe valve M out to its normal position. By this arrangement of thumbvalve, it will be readily seen that the valve E, can be opened to adegree proportionate to the pressure applied on the valve M, and in allcases owing to the taper of the stem m the rising of the valve E will begradual. This result is very advantageous, as heretofore in atomizers ofthis kind, when the thumb valve is operated, the check valve wouldgenerally be thrown wide open. In the construction shown the escapeorifice, under valve E can be regulated by the pressure of the thumb.

In operation after air is stored up in the bulb K, and it is desired toapply the powder by simply pressing on the thumb valve, the valve E willbe raised and the air contained in the said bulb will pass down intochamber G, into the vessel up through channel H, and out through tube I,it drawing the powder from the bottle by induction as it passes.

In Fig. 4 I have shown a modified arrangement of the powder spray tubeand air controlling devices. In this construction the storage bulb andthe intermediate valve devices are dispensed with and the compressingbulb secured direct to such tube. In this construction as in the otherthe device is operated by one hand, leaving the other free for and thestopper with which they are connected, by means of tubes, said stopperhaving an air passage therein, a valve and its operating mechanisms, aspray tube connected with the air discharge passage, said tube having anozzle or nipple intermediate its ends, and a powder bottle or holdersupported upon said nozzle or nipple, substantially as shown anddescribed.

2. An atomizer, comprisingaholder or main chamber, a stopper having acentral chamber in its top, having oppositely extending orifices, astorage bulb, connected with one and a compression bulb with the otherof such orifices, said chamber communicating with the holder and havinga spring valve normally closing off such holder, a valve operating meansoperated from the outside, and a spray tube connected with the dischargechannel of the stopper, all substantially as shown and described.

3. An atomizer comprising a holder, a compression bulb, a storage bulb,a chamber connecting such bulbs, having a removable top, and having anaperture in its bottom communicating with the holder, a spring valve,normally closing such aperture, and having a shank extended through theaperture, a push valve having a tapering end adapted to engage suchvalve stem, and the spray tube and discharge channehall arrangedsubstantially as shown and described.

4. The combination in an atomizer, of a holder, a stopper closing themouth thereof, having a chamber in its top, having a removable cap, andnozzles projected through the opposite sides of the stopper, a dischargechamber, having a connected spray tube, an opening connecting suchdischarge and the top chamber, a second chamber projected rearward atright angles to the first chamber, a thumb valve held to operatetherein, having a tapered end, and a spring actuated valve held tooperate in the upper chamber and having a stem held to engage the stemof the thumb valve, all substantially as shown and described.

5. The combination, in an atomizer of the kind described with theshifting valve, between the bulb discharge orifices of a cham her havingan apertured screw cap having an internal annular flange, a thumb valvehaving a button projected through the cap and formed with a flangeabutting the cap flange, said valve having a stem held to engage theshifting valve, and a spring held about the thumb valve to normallyforce it to its normal position, substantially as shown and described.

In testimony whereof I afifix my signature in presence of two witnesses.
